The main changes compared to EN 1254-8:2012 are:
— improved alignment with plastics and multilayer pipe standards for hot and cold water
applications;
— separation of test methods into part 20.
!The need for an amendment was based on the following points:
— editorially correct “lifetime up to fifty” by adding “years” in the scope;
— update normative references;
— include a wall thickness requirement for copper alloy fittings used in systems according to
EN ISO 15874, EN ISO 15875, EN ISO 15876, EN ISO 15877, EN ISO 21003 and EN ISO 22391."
